Abstract - Gas leakage is a common problem in various
places, including residential properties, industries,
manufacturing facilities, and gas stations. For example, LPG
(Liquified Petroleum Gas) is a highly combustible gas which
can lead to building fire, suffocation or an explosion.
Methane explosions, which occur when a buildup of
methane gas, a by-product of coal, comes into touch with a
heat source, are highly prevalent in coal mines. This can
lead to coal mine fire and severe life damage. One of the
preventive methods to stop this kind of dangerous accidents
associated with gas leakage is to install gas leakage
detection systems at vulnerable places. The aim of this IoT
project is to build a model that can automatically detect,
alert and minimize the chances of calamity. The gas sensor
which is used in the model detects any type of gas leakage.
Once the sensor detects any leakage, it will send the data to
the raspberry pi from there it will be uploaded to the cloud.
On cloud the sensor data will be analyzed to determine the
severity of the situation and actions will be performed
accordingly. If the situation is detected as low (no leakage)
no action is performed and the device continuously collects
the sensor data. If the situation is detected as high
(Leakage), then all the concerned persons are notified via
MQTT dashboard app, buzzer will go off and the relay is
turned on to perform preventive operations. Our model also
predicts the air quality index of the surrounding based on
the sensor data using Machine Learning algorithm. With the
help of this model, we are able to achieve our aim and we
are able to reduce the damage as much as possible.

1. INTRODUCTION
making gas detection challenging in real life. Gas leaking
causes serious accidents in everyday life.
LPG is the most common gas used in households and
industries. LPG consists of gasses like propane and butane.
These gases are highly combustible. LPG gas is also used as
propellant, fuel and as a refrigerant. When the leak occurs,
it may cause an explosion. The death rate due to LPG gas
leakage and their explosion has increased. Therefore, the
leakage should be controlled to protect people from
danger.
In past accidents like the Bhopal gas tragedy on December
1984 more than 3000 people were killed when methyl
isocyanate was leaked out. Andhra Pradesh's Nagaram
The line became rusted in June 2014, resulting in a gas
leak, a blast at the Gas Authority of India Limited's plant,
and the deaths of 29 persons. So, to protect people from
this hazardous disaster we need to upgrade the
technologies.
Sensors are crucial part in our model. There are various
types of gas sensors such as MQ2, MQ5 which are used to
detect different types of gas in the surrounding.
Our proposed methodology is utilized to identify gas leaks
and send out alert messages to those who need to know. It
can also be used to determine how much gas is present in
the environment and communicate that information to the
user. This system sounds an alarm when a gas level
exceeds a preset threshold and also performs preventive
maintenance.
2. RELATED WORK
[1] Subramanian M Athish developed a model to detect
gas leakage with push notification feature. The system
using a lighter that releases a gas we want to detect and
for this he is using MQ5 sensor. As the gas is leaked the
There are many different types of gases that play a vital
role in human life, and some of these gases are odourless
and colourless, therefore they are not detectable by
human senses. The majority of people lack sufficient
knowledge of how to handle gas-powered products,

Buzzer light is turned on and notification from push bullet
is send to the user.
[2] According to the author of this paper, LPG is
commonly used as a fuel in homes, companies, and
automobiles. The United States Bureau of Mines
investigated gas in 1910, initially developed by Dr. Walter
Snelling, to see if there was any explanation why it
dispersed so quickly, and discovered that the vanishing
gases were propane, butane, and other light hydrocarbons.
Both LPG and gaseous petrol are natural friendly and may
be easily distinguished. These gases are usually stored in
pressured steel chambers in a fluid frame, where they
dissolve at normal temperatures. LPG is heavier as a result
of the air correlation; it flows down the floor and settles
into cosy depression regions, making it difficult to
disperse.
[3] According to Chaitali Bagwe, GSM is an extension of
the internet notion. GSM refers to the use of the internet to
connect multiple physical devices. Sensors are wired
together in a physical device. The data collected was sent
across the internet from one device to another. Using the
GSM principle, the author created a novel gas alert system
[4] Rohan Chandra Pandey used the internet to create a
new method for gas notifications. This system was
designed to detect harmful levels of LPG gas and send an
alarm to the user. This system displays the value on the
LCD panel. The buzzer goes off when the gas level reaches
the threshold value, and the ARM board sends an email to
the user via the internet.
[5] Gas leakage and gas sensing, according to
Anandhakrishnan S, is a difficult issue in today's world.
The majority of the gases are very combustible. The goal of
this planned method was to prevent unwelcome kitchen
difficulties. This technology was primarily used to detect
gas levels and send individuals SMS alert messages. Gas
wastage in the home and industry was also tracked using
infrared sensors.
3. MOTIVATION AND PROBLEM STATEMENT
Gas leaks cause a variety of consequences, including
financial loss and human life. The environment has a
critical impact in human health issues in everyday life.
Fire, suffocation, and explosion risks are all determined by
physical attributes like as flammability and toxicity. The
number of people killed by gas cylinder explosions has
been rising in recent years.
These are some of the model's specific problem
statements:
• Gas leaks have a variety of consequences, including
financial losses as well as human life.
• Inhaling leaked gas in an inside space, like your home
may end up in an exceedingly lack of oxygen within the air
and cause hypoxia.
• Leaked fossil fuel mostly methane may be a powerful gas.
it's a big contributor to global climate change and also
contribute into smog which causes asthma and other
respiratory problems.

measure the humidity and temperature which will be

2. To determine the level of gas leakage and alert the

3. To perform preventive operations and to predict the
upcoming gas leakage based on previous data using
Machine Learning Algorithm.

7. METHODOLOGY
Fig-2: Flow-chart of the model
This is the methodology we used in our model:
1. First the system is turned on and the gas sensor start
reading the gas concentration
2. System then determine if the gas leakage is there or not.
3. If the gas is not leaking then it continues to read the
data.
4. If the gas is leaking then it determines the severity of the
gas leakage.
5. If the severity is of high level system will start the
buzzer and alert the concerned person and start the
preventive operation.
6. Air quality is also predicted with the help of data on
cloud server and prediction model and is displayed on the
MQTT dashboard app.
7. It will keep on reading the data using gas sensor.

9. CONCLUSION
In terms of safety, the proposed gas leakage detector looks
promising. During the development of this prototype, the
goal was to create a revolution in the field of safety against
the leaking of hazardous and toxic gas in order to reduce
and thereby eliminate any significant or minor hazard
caused by gas leakage. The proposed method
demonstrates how a gas leak can be detected and the
harm caused by it controlled. Once a gas leak has been
identified by the sensor, an alert has been sent to the
appropriate person, who will take appropriate preventive
action. One of the most important benefit is that the data
can be accessed from anywhere around the globe. The
model is very much reliable and secure as MQTT protocol
is being used for communication between raspberry pi
board and user i.e MQTT dashboard mobile application.
Relay has been added in the model to perform different
preventive operations as per requirement such as
switching on the ventilation fan.
